- Did you ever sit under the clear night sky and wonder “does it go on forever?" The size of the universe has long been a question that has puzzled scientists, philosophers, and theologians, without a clear answer… well, until now. In this video, Fermilab’s Dr. Don Lincoln leads you through what modern science can say about the size of the universe.

Thanks for understand I'm so die for tired my lifetime thanks all
When my dog gets a treat from my left hand she was expecting to be in my right, it blows her little mind...completely.
That is what this video is doing to me! Thank you Dr. Don!
Check out Inside Animal Hearts and Minds: Bears That Count, Goats That Surf, and Other True Stories of Animal Intelligence and Emotion-- Book by Belinda Recio ..it has some remarkable stories all sourced to actual published research papers listed in back of book or from the scientists themselves.
I hate to give away one of the more powerful examples shared but ... It concerns an orangutan who had been taught and who knew sign language and was able to make basic statements& ask simple questions. True story.. One evening the orangutan was outside with their scientist care taker and got the care taker's attention and then pointed to the Moon and then used sign language to ask:"What is that?"
Poignant for several reasons not just animal intelligence but also like a time machine or window to what early humans and hominids having those or similar early questions... is almost proto science by nonhumans too..
@@hb-youtube this is great, and thats actual same with humans, we(if we care and are curious) gonna try to learn something new, i just wonder if other animals would be more intelligent, what they would ask!?
That's funny. I play guess which hand with my dog all the time. He sniffs it out. What really gets him is when both hands are empty. Then he goes behind my back and grabs it. I hear a dogs sense if smell is 10,000x better than humans. Yet the most offense stench doesn't bother him in the least bit. Go figure.....
Stop doing that to your dog!! 🐾🐾
So well explained, and enlightening!
Thank you so much.
More videos are welcome on Space and Universe. The subject is very complex but, still easy
to follow your slow and precise narration.
"It's a complicated calculation but a straightforward one".
Not falling for that one again.
That's like "It's not a question if, but when"? Overused for sure.

I wish this man was my science teacher when I was in high school. Now at the age of 40 I love listening to his presentation here in CZcams. It's so calming and informative at the same time. 😃
Dread Inside,
He probably wishes that as well. At 40 it isn't too late to study the material you didn't get when you were young. The only difference now is CZcams presents a much better learning format than any classroom format. With CZcams you can pause a lecture, study any necessary background information needed to understand the content, then, go back to the video.

@@postholedigger8726 , you are right. The best thing about the world wide web is that you are not tied to only one train of thought, you can listen to people from all walks of life from all around the world.
I do feel the same. However, this knowledge is relatively new and complicated in detailed so that our K12 teachers didn't have any chance to transfer it to her/his pupils. But now we can learn from Dr. Don.
Maybe if he was a teacher he'd find himself so hassled with disruptive or apathetic students, lesson schemes and evaluation, endless meetings that he'd have little energy left to enliven his teaching
So you need someone to calm you down? 😂
What a good explanation. Space, physics, astronomy, all they are fascinating.
Dr., sir i found your channel by chance. This is best explanation ever.
This guy is a really great presenter. One of the best on you tube. Whoever does the scripts does a great job as well.
Blue rectangle from 15:56 - 16:03
This is not a "good presenter guy", he is an actual scientist who has some very significant acomplishments
In 1995, he was a codiscoverer of the top quark (...) was a member of the team that discovered the Higgs boson in 2012. (wikipedia). Actually these are kinda public lectures of a decent scientist working in/with a very important scientific institution.
I'm sure the presenter guy appreciates your kind words. I'm also sure that the presenter guy is the script writer.

One of my favorite quotes by Douglas Adams:
> Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Booting up my Total Perspective Vortex so that I can see all 23 trillion light years at one time...
Next video should be, How big is the "Whole Sort of General Mish Mash"?
This about sums up how and why this is al a fantasy. If this were true, there would be actual measerments and numbers.
Scientists saying space is big, that is no science man, it's deceitfull fantasies...
Man.. who makes this stuff up? The Balooney Tunes? 🤣😂
@@123bug Try to measure Earth's diameter without being able to travel, and lets see what numbers you are able to come up with.
@@samuellourenco1050 yeah so were Just talking a bunch of numbers in the air... It doesn't matter if you add a zero... It is still HUGE! The scientists have discoverd someting people: space is HUGE! 🤣😂 BTW this was pretty hard to type spinning with 60 MPH 🤗
I can watch these videos over and over cause Ill never really grasp the grandiosity of it, lol. Its just mindbending, that humans are capable of such feats. Thanks Mr Lincoln for the great moderation. :)
I come back to these videos every few years and it truly is amazing how much and how little we know at the same time. How big and how small we are. It messes with our primitive ape brains thinking about such scales
PLEASE, show at the least, a modicum of due respect for "Professor" Lincoln.
Fantastic video and a new subscriber. Thanks Dr. Lincoln.
Thank you for this video. Great content!
Have never ran into this channel, and just saw this in my feed, so I thought I’d give it a go. Was beyond fascinated with the science taught. You got a new sub out of me! Tyvm! Looking forward to binge watching your channel now 👍
Ha gayy
Thanks for all these great vids. Fermilab is my favorite science channel! Dr. Don explains it well!
It is amazing that we've come in a century from the point where Eddington was asked whether it was true that only 3 people understood general relativity, and answered "who is the third?" (may not be true, but), to the stage where the general public can follow beautiful youtube videos dealing with topologies of the universe. GR is nowadays seemingly something for schoolchildren!
It has always been for school children, except most people have given Einstein too much credit over the decades and feared, no thanks to pop culture, stating that obvious publicly. I will assume you meant General Relativity.

But our probes went futher.

Awesome presentation, Dr Lincoln 😃
Thanks a lot for your excellent presentation. Instructive, concise, and easy to understand. Just wonderful!
The entire video, the entire series, the entire Fermilab channel is fascinating, and we are so fortunate that you chose to share the fascination of physics with me and other physics aficionados.

Yes. Don Lincoln has the most understandable explanations of physics.
Of course the universe is a buble. It appears flat because of unfathomable expansion.
Carolyn, question things rather than blindly following what you hear. Read my comment above and decide for yourself.
I was looking over the calculations on the chalkboard behind you and it appears you forgot to carry over the 1.
Johnny CincoCero 😂😂😂
I think that you may be correct but if you divide 1 by X-bxy the correct answer is reached ,ie the thinking explained in this video is entirely mind boggling and apart from speculating until new science is developed we can only ponder the inponderable!!

You are all wrong ...it’s a picture of a waitress note book , taking orders in a diner

Absolutely impressive explanation. A complex topic explained in simple words. Thank you!
The reason it's simple and that you understand it is because it's wrong. The universe is both infinite in size and age.
@Hank Trucker precisely, and what is more, if we are to conclude it's approximate infinity and the endkess, infinite extension of it's approximate infinity, then we must thereby conclude that it's very existence is imaginary within the confines of the space-time continuum , in the sense that it is only the moment in which we are experiencing time that actually exists and therefore since nothing is in fact real we are all at perfect liberty to take mushr⚪⚪mzZZ and LSD , with which we can experience it's existential paradoxical illusion until the cows come home to roost!
@@HankTrucker The arrogance in many people borders on disgusting and dimwittedness.
Many actually honest people find that in basic and simple terms, Occam's Razor applies to all things.
"Absolutely impressive explanation. A complex topic explained in simple words" is true.
You wont win this. More to come...
Many thanks, great joy to watch your videos.
i'm glad that you came back with another wonderful lesson
This was a really good video about truly mind-bending astronomical ideas. Thank you for creating and putting this video on CZcams.
It is "mind-blowing" and in all rational aspects, seemingly inconceivable. Might as well be infinite if the visible universe is 92 billion light years in diameter but its actual size 250X that. Great video explained thoughtfully and clearly. Bravo Professor Lincoln!
But they don't know that, it's just an estimate until proven.
@@ENGLISHISBEST I believe his "...250X" use made that clear.
This channel is amazing. This contents should be in every school
I have been fascinated with space since I was a child. Unfortunately I’m physics and mathematically challenged. Thanks for making this awesome knowledge understandable for people like me.
Yeah me too love it ive got books and books on space its just so facinating till theend of time.
no matter how smart we are how advance we are but compared to the Universe we are nothing, the mystery of the Universe has nothing to do with math, physics but in the eyes of scientists they think that human intelligence someday may solve it, nah we are curious but at the same time we are delusional and arrogant, the mystery of this Universe is not a mathemathical problem, it is beyond our understanding
Dear Don,
You routinely blow my mind, my mind hurts....
THANK YOU FOR THAT!
I LOVE the videos! I think it's wonderful that you're doing them. And, thanks for that, too! 😊
A very good and "simple" explanation of the seize of the universe, and that is very good with numbers this big 👍
This stuff is above my pay grade, but you make it interesting and much simpler to understand. Thanks and subscribed.
Welcome back, Doc, we missed you!
Brilliant expose and breakdown.
I love this channel to the edge of the universe...and back.
Enjoyed this, cheers!
It's amazing how philosophers like Aristotle and Ayn Rand have reached the same conclusions. Brilliant individuals!
I’ve watched maybe 6-7 videos of this person. So far this is the best one, because it’s the most comprehensible one, the others not so much.
The thing I liked the most is realistic admission that yet we don't know a great deal. Every answer presents a new query about nature.
Just saw your video for the first time, I AM HOOKED!
The most beautiful thing about the conversation is infinite possibilities, Merry Christmas!
Brilliantly explained! I have heard so many attempts to convey this topic and this was the most salient and clearly conveyed of them all. Well done! x
Don Lincoln knows how to explain the complicated in simple and visual terms. He's brilliant and I love his videos.
Fascinating stuff. He really does well explaining to the viewer in layman terms about a subject that most people know nothing or only a little about. Plus those of us who have a passion for learning more about life , the multiverse and everything
But while he was presenting this, he was forgetting Uli's goodbye cake.
Assuming that there is a 'multiverse' which is only an unproven theory, aka a guess.
@MZT Then why don't you straighten it out with a video of your own? Since you've already listed his mistakes, surely you know the truth about the whole universe...right?
@@mzt2929 Exactly what Einstein and many other scientists many times gave us and still do. I use Einstein as a named example due to most people being familiar with him than most other, actually better scientists.
Very poor explanation. He didn't explain anything clearly.
Totally enjoy the presentation and the presenter. So informative. Ok, so now what is on the other side of the edge of the universe?
That is the $64,000 question dm. Heaven? Hell? Another universe? A so-called 'multiverse'? Nothingness? Good question .... and one that could drive a sane person nuts just contemplating it .... good thing I'm half nuts to begin with. 😂🤣
I've always liked this channel. Very well done.
Fascinating facts in a beautiful and easy to understand style. Thank you Mr Dan. I also love the intriguing novels of your name sake, Mr Dan Brown.
I think the thing that is mind blowing is not just how big it is, but that no matter which direction, you're always looking towards the beginning.
Yes. That's what yo momma said and I nodded in agreement 🤣
Excellent presentation!!!
It's really, really difficult to explain complex topics in simple terms. And to do it with wicked humor is truly enjoyable.
Boil that dust speck.
This channel and PBS SpaceTime give me my cosmology fix.
You have that special talent to explain complex subjects in a more easy way to understand ! That is sure a gift Dr. Lincoln... I enjoy a lot to watch your video''s here ! Thank you !
Did your son write this? Careful not to say dad!
Fascinating thought processes!
13:22 I think you meant to say " If the universe is flat" :) You have one of my favorite YT channels thank you so much !
No, he did mean to say that. Listen for like 30 more seconds. He's saying that, from your point of view the earth's curvature is relatively small, and so for measurements at that scale it wouldn't really matter if the earth was flat or round. You don't count the Earth's curvature into the equation, when you're using a tape measure to see if your new couch is going to fit in your living room.
Great detail and explanation. Thank you
Amazing. Kudos for the simple way of explaining. It blew my mind, I always considered a closed “infinite” universe, now I have two other views to take into consideration. Congratulations!
Three views... And he said a closed universe NOT infinite.

Hooked on the vids Big D. Wish they came out more often.
Fascinating but completely incomprehensible to me. I'm thankful that I came across this video because now I have a place I can go to learn as much about the universe that I'm capable of learing.
Incomprehensible is a mighty long word. It’s got 5 more letters than mockingbird.

@@soldtobediers as it’s been said before ,science is the discovery of God mind.
@@soldtobediers You can't be that foolish, that you believe some sort of god has anything to do with this! god is just invented by humans that couldn't understand how some natural events took place. Things that we now can explain were very difficult to understand in the old days. For instance: A rainbow was supposed to be a sign of god that there would never be a deluge again! That deluge never happened anyway, that;s completely impossible, there has never been that much water on earth, so where did it come from and where went it after the so called deluge?

We can never know for this simple reason: determining where the edge is depends on the light we receive from that edge; that light has reached us.....but any light beyond that has yet to reach us remains hidden.....so, we can not know if anything at all lies beyond.
Absolutely the size of the universe is measurable, the problem is Stanley just hasn’t made a tape measure big enough yet. Until then this was a great video!

if you could make tape measure as fast as speed of light then space would be faster expanding than you could make it. If you could make it faster than expanding of the universe you might eventually see your tape measure reach you behind you and touching your back while you are rolling it forward faster than universe expanding.

From the combination of the 2 times he said this and the context, it sounds like this was on purpose, to show how observation from a commonly used vantage point (which, in the case of trying to observe the whole universe, we don't have a choice) can fool you.
The universe is 1 universe long and 1 universe wide. It has a depth of 1 universe and it weighs 1 universe. It takes 1 universe years to travel across the universe.

This was the best explanation of the cosmic microwave background. I think I finally understand it. Might have to watch it a few more times though :)
Its not actually very hard to understand, to put it as simple as possible, its residue of "cosmic explosion" but the thing that im not sure is how they(people who made instruments) knew that what they see is measure of microwave from "big bang" and not some "other" cosmic event that instruments measured.

What’s outside the universe that it is expanding into? Empty vacant lot?
@@robpagan1 Either an empty vacant lot not yet filled with matter or a very puzzling "non-existence", as space itself is being stretched along with the expansion of matter and energy (as a side note, space itself -or rather spacetime as we would be more correct in calling it- is pretty interesting even if void of usual matter and energy, as it is still home to quantum fluctuations that can generate particles from nothing. That is a concept I still have to deeply understand and wrap my mind around). The Universe thus would be a growing bubble of sorts, not necessarily round per se but an enclosed space; all of this geometry mentioned here and in the video happening at more dimensions than we as humans can visualize (and the number of which is still being debated by scientists). This whole universal system is possibly happening in a several-dimensional "sea" of Universes (in which Universes "happen": are born, grow and end -maybe interact?- in a realm where time as we know it either doesn't exist at all or exists interacting with any number of yet unknown forces and energies through these additional dimensions in ways that we can't possibly conceive any time soon). The Existence is awesome!
Nice
Super video - just got confused when you switched from degree meaning temperature to degree meaning the arc subtended by an angle. But other than that it was fabulous.
watched again - sphere is just a 2-D analogy - if you head off in the Z direction in closed 3-D space and return to the same point what does that shape even look like?
Where can i pick up one of those Einstein Tee's you're wearing? Knowing where and how would make me infinitely happy to do so. Thanks and Happy New Year 2023.
These videos are so very amazing 💪🏻❤️
Humans tend to think in terms of everything having a beginning and an end. To think that the universe just keeps going, with no end, is mind blowing.
Their are never ending universes, let that sink in.
Coi Pansat if time is an illusion then nothing makes any more sense than anything else as you have no order of events.
David Gagliardo @ because the universe had a beginning we think everything has to have a beginning but I don’t think so.
our problem is we currently calculate time as a separate linear dimension. like velocity is the distance traveled divided by the time traveled. we have to redo that equation and instead describe time as a spatial relationship. time isn't separate from space, but we think of it as if it is. time is the relative change between space and the same space. it is not a constant.
I don't know, that it had no end seems like the natural conclusion to me. Closed just seems like a limited frame of reference.
